According to uniquenutrition.net:L-Huperzine A is a natural plant alkaloid (extracted from Huperzia serrata), which quickly and potently boosts memory, learning, and concentration. Used worldwide for decades in adults and high school students. Is considered the most potent short term memory enhancer available.

Overall it is just a mix of well known substances but it doesnt especify quantities so no way I am taking it without knowing exactly how much huperzine A plus Choline plus vinpocetine is going in to my system. Not to mention I have no idea how legit that company is and it would be advisable to get those components separately.
